Windows 7: AC 97 audio not working...Help pease.

I installed windows 7 in my relatively old desktop. Everything is working fine even USB audio but my headphone and microphone not working. Windows downloaded ac97 by itself but that is also not working. there is a cross on speaker in system tray. I tried to install various ac 97 drivers but windows are not accepting that saying not signed.

From the looks of things you are trying to install a Realtek driver for a C-Media audio device. That in itself presents a problem as C-Media has dropped all support for their older audio chips, but not a total loss.

Actually I tried every possible driver I found on net but of no use. Then I remembered the CD I got with my desktop. I found the AC 97 driver there and installed that. It is an old driver of 2003. Everything is OK now.
